high Idle problems

11-24-2010, 03:26 PM

noticed a problem more and more frequently in my 97 Grand cherokee laredo. on cold startup it refuses to idle, it only starts with the assistance of me giving it throttle. i then have to maintain the throttle to keep it running and manually controling the idle with my foot. after warming up it seems to be fine, when the low idle would kick in. have checked the alternator, tps and the fuel pump, all seem to be in good operation and with in specs... looking for any tips. 97 grand cherokee, 4x4, 4.0 6 cyl 160k miles
